my son receives food stamps of $292 a month can I still claim him on my taxes. He still lives in my house and does not work.

Possibly.  If you provide over half of his support and he does not make more than $5,050 a year, then you can claim him as a dependent on your return. 

To claim someone as a Qualifying Relative, they must be:

• Your child ( including step children, adoptive children and foster children) or a descendent of them
• Your sibling (including half siblings) or a child of your sibling or a sibling-in-law
• Your parent or grandparents, including step parents and in laws
• Any other person that lived with you for the entire tax year
• Not a qualifying child of another taxpayer
• Someone that you provided over half of their support for during the tax year
• Has less than $5,050 in income (not counting social security)
